Sprung pillow

Abstract

A pillow comprises an outer pillow shell case defining an inner pillow filling cavity for receiving filling material, wherein an internal member is provided inside the inner pillow filling cavity and attached to opposed ends of the outer pillow case shell, the internal member being configured to limit lateral expansion of the outer pillow shell case when the pillow is compressed in use.

The invention claimed is: 
     
       1. A pillow, comprising:
 an outer fabric pillow shell case defining an inner pillow filling cavity for receiving filling material, and 
 an internal member inside the inner pillow filling cavity and attached to opposed ends of the outer fabric pillow shell case, the internal member being configured to limit lateral expansion of the outer fabric pillow shell case when the pillow is compressed in use; 
 wherein the internal member comprises an internal divider operative to divide the inner pillow filling cavity into two internal filling cavities, the two internal filling cavities comprising a top cavity and a bottom cavity; 
 wherein the internal divider comprises an open framework comprising one or more apertures; and 
 wherein the open framework is formed by a pair of X-shaped members. 
 
     
     
       2. The pillow of  claim 1 , wherein downward force of a head resting on the pillow causes the internal member to bow downward in a center location, resulting in pulling forces on edges of the internal member attached to the outer fabric pillow shell case creating a curling upward rounding of the outer fabric pillow shell case and filling material. 
     
     
       3. The pillow of  claim 2 , wherein the internal divider acts as a spring. 
     
     
       4. The pillow of  claim 1 , wherein a first of the two internal filling cavities is filled with a first quantity of a first filling material and a second of the two internal filling cavities is filled with a first quantity of a second filling material. 
     
     
       5. The pillow of  claim 4 , wherein the first quantity is the same as the second quantity and the first filling material is the same as the second filling material. 
     
     
       6. The pillow of  claim 4 , wherein the first quantity is the same as the second quantity and the first filling material is different to the second filling material. 
     
     
       7. The pillow of  claim 4 , wherein the first quantity is different to the second quantity and the first filling material is the same as the second filling material. 
     
     
       8. The pillow of  claim 4 , wherein the first quantity is different to the second quantity and the first filling material is different to the second filling material. 
     
     
       9. The pillow of  claim 1 , wherein the internal divider has a width smaller than a width of the outer fabric pillow shell case when the outer fabric pillow shell case is unfilled. 
     
     
       10. The pillow of  claim 1 , wherein the internal divider has a height smaller than a height of the outer fabric pillow shell case when the outer fabric pillow shell case is unfilled.
